34、mation. Inspection lots shall comply with the lot formation provisions of MIL-A-48078. 4.4.1.1 Forqinq lots. Forging lots shall contain body forgings from not more than one heat of steel, that have been heat treated in the same heat-treatment equipment, at the same temperature, in one unchanged proc
35、ess. The forging lot thus constituted shall be the basis for the selection of samples for the tension test hereinafter p rescr i bed. 4.4.1.2 Cold shaping lots. Cold shaping lots shall contain cold shaped bodies, from not more than one heat of steel, that have been cold worked by the same process, u
36、tilizing the same tooling and equipment and stress relieved in the same furnace at the same temperature for the same length of time. The cold shaping lot thus constituted shall be the basis for the selection of samples for the tension test hereinafter prescribed. 4.4.1.3 Miscellaneous lot. Small lot
37、s, such as bodies from abnormally small heats of steel or bodies which have become separated from previously delivered lots, etc., may, at the discretion of the manufacturer, be grouped into miscellaneous, forging, cold shaping or casting lots as the case may be. Such lots shall be identified by a m
38、iscellaneous lot code number. 4.4.1.4 Groupinq. Forging, casting, or cold shaping lots shall remain grouped together for lot identity purposes, according to forging, casting or cold shaping lots, until such time as the results of the tension test have indicated that the lot has cornplied with the me
39、chanical properties requirements of the applicable drawing. 4.4.1.5 Projectile lot. All forgings, casting or cold shaping lots that have been determlned to have complied with the mechanical properties requirements of the applicable component drawing, may be re-grouped for assembly into projectile lo
40、ts. A projectile lot shall consist of projectile assemblies produced by one manufacturer, under one contract, in one unchanged process, in accordance with the same drawing, same drawing revision, same specification and same spec i fi cat ion rev is ion. 4.4.2 Examination.
